MULTIPLE-WRENCH TOOL.

To all fr0/1.0m t may concern."

Be it known that I, ALBERT D. GRovER, a citizen of the United States, and resident of New York, county and State of New York, have invented certain new and useful Improvements in Multiple-Wrench Tools, of' which the following is a specification.

The object of my invention is to provide a. new and improved wrench which is small and compact and is readily adjustable for nuts of different sizes. The instrument consists of but few parts and is so small that it can be carried about in the pocket.

The objects and advantages of my invenw tion will become apparent from a detailed description of the accompanying drawings, which show a preferred embodiment of my invention.

In these drawings,

Figure 1 shows my new and improved wrench tool in side elevation, the wrench' member being locked in operative position;

Fig. 2 is a longitudinal cross-section on line 2-2 of Fig. l;

Fig. 3 is a View similar to Fig. 1 with one of the handle plates or members removed for the sake of clearness, the parts being shown in such position that the tool may be used as a screw-driver; and i Fig. 4L is a transverse cross-section on line Li--Aof Fig. 1, looking downward.

On suitable form of handle 1 is pivoted a rotary wrench member 2 by -means of a stud 8. In the present instance, i have shown the handle 1 as consisting `of a pair of plates secured together andl properlyl spaced by the shoulder rivets or studs 3 and 4. If desired, however', the handle need but consist of a single member.

The wrench member 2 is provided with a series of jaws 5, 6, 7 and 8. The number and different sizes of these jaws may vary to suit the particular purpose for which the tool is intended. In the particular embodiment illustrated in the drawings, the wrench member 2 is intended to be used for adjusting the nuts of banjos of different sizes.

Between the handle members 1, is mounted a slide 9, best shown in Fig. 3. This slide is supported and guided by the studs A and 10. The stud l() is preferably not riveted to the handle, so as to allow the same to spread apart slightly at the center, for. reasons to be presently explained. The slide 9 is provided with slots 11 and 12 which Specification of Letters Patent.

Vin the form` of a suitable tool.

Application filed August 16, 1917. Serial N o. 186,460.

the slide -9 is provided with a pair of lati eral locking extensions 15, soconstructed andarranged as to engage the shoulders 16 of the rotary wrench member 2, whereby the latter is securely locked in operative position. This is clearly shown in Fig, 1.

in the present instance, the shoulders 16 are formed by cutting notches in the periphery of the wrench member 2, but it is obvious that they may be formed in any other suitable way.

The slide 9 is also provided at its lower end with a central extension 17 adapted to engage one of the shoulders 1G of the rotary wrench member 2, when the slide 9 is to be usedv in withdrawn position, as indicated in Fig. 3. The outer endrlS of the slide 9 is Obviously, in the broad aspect of my invention, the particular form of function of the outer head 18, which may be referred to as an operative head, is immaterial. For. the sake of illustration l have shown the head 181 as a screwdriver- When the slide 9 is in inner or wrench-locking position, as shown in Figs. 1 and 2, the central extension 17 rests in one of the jaws of the wrench member, and the head 18 lies within the handle 1. This not only keeps the screw-driver head 18 out of the way when the instrument is used. as a wrench, but it also makes it easier and safer for a person to carry the tool in his pocket. Y

Vhen it is desired to use the head 18, in this instance a screw-driver, it is only necessary to grasp the slide bythe lateral projections 19 and pull it out until the central eX- tension 17 is clear of the wrench member 2, whereupon the latter may be rotated until one of the notches 16 comes beneath the eX- tension 17. 1n this position of the slide 9,

`the head 18 projects beyond the handle and the instrument may be used as a screwdriver, or whatever tool the head 18u may' represent. Any thrust or pressure brought to bear upon the slide 9 when used as a ,screwldriver or. other tool, is takenup by the wrenchmember 2, asv will beclear fromV y Fig. In other words,V when the head 18 is in operative position, the wrench member r2 constitutes a support or bearing for the slide 9y to prevent longitudinalY inward movement of the "slide and head. i The slide 1 `9-is Yfurther steadied inv its withdrawn position by the pressure of the 'frictional projections 13 against thesides of the slidefV As previously' stated, the studV 10 is notriveted i tothe handles 1 butis merely used as a a guide and allows the handles to serve as springs when the slide 9 is meved from one position to the other.

Asmaybe-seen'from Fig. 3, although the wrei'ich'ja'ws 5, 6, 7 and Sfare of different Y widths tol-fit onto nuts ofdifferent sizes,they `are 4of Vsubstantially the samedepth. This featureloflconstruction enables. the extensionll vof the slide 9 to project fullyinto the-jaws, thus insuring full andiirniV contact between the lateral locking extensions ber2. f1 If; desired, the slide9 maybe provided with 'one or more lcutting edges 20 which are 15 Yand thefshoulders 16 o'f the wrenchme'meXposedfor usebythe cut-awayjportions ,Ql'off the handle, best'shown'in Fig. 1.

These knife or cutting edges may serve various purposesf-such as, insulation Scrapers,

i banjo string cutters, wire cutters, etc.

l.'Itwill bejseen Vfrom the foregoing, that I have'provided' anvr exceedingly simple, compact and eiiicient 'tool which embodies sev- 'eral Vusx-iful instrumentsin one The wrench LmemberQ is readily-'adjustable to briiigfany ""tu-rnl the wrench wheel.2 into such position thatV one* of the vnotches A16;*will come into alinement with the central extension 17 of Byfproi'fiding Ythecutting edges 20 near i the lateral finger pieces '19,thelatter act as -af guard or protection against a person accidentallyV cutting himself on the knife edges 20: When the slide is' in extended povsition,'as showninyFig; f3, the knife edges QO-a'rein*concealed position. kAlthough I haveherein shown twoknife edges, it is ob- Vvious `thatbut` oneAis necessary.' i

For,H delicate work, such 'as Aadjusting nuts j' on banjos" and-the Alike,"the toolfof my invention maybe made; very smal-land flat, so

V` that it? mayfbelcarri'ed in the pocket, theV n sameY as f an ordina-ry Y pocketk knife. `For heavier work, the Vparts will, of course, be

)inadefstrongerland correspondingly larger. Although I have herein illustrated and i Vdescribed aspecif'ic form lof tool, I will have understood that Ido not intendto belim- `ited to the precise details of construction set forth.
